Abstract
Description
Technical Field
[0001] This utility model relates to a high-precision floor grinding and polishing machine, specifically a high-precision floor grinding and polishing machine. Background Technology
[0002] Floor grinders are mainly used for grinding and treating floors. They can effectively grind terrazzo, concrete surfaces, epoxy mortar layers, and old epoxy floors. Floor polishers are used for grinding and polishing the surfaces and undersides of marble, tiles, etc. They are characterized by being lightweight, flexible, and highly efficient.
[0003] Announcement No. CN214722915U discloses a floor grinding and polishing machine. By incorporating a helical spring and connecting shaft to buffer vibrations, it can apply a certain pressure to the ground during processing. Multiple friction discs are used during grinding, resulting in higher efficiency and a smoother polished floor compared to traditional single-rotor grinding devices. This reduces the need for subsequent rework. Furthermore, different types of friction discs can be mounted on the lower end of the mounting shaft for simultaneous grinding and polishing, offering greater flexibility and making it more readily accepted by users.
[0004] However, during the implementation of this device, the friction disc is driven by the cooperation of gears and planetary gears to complete the grinding of the ground. Since terrazzo and concrete are building materials, many small stones remain on the ground after installation. The gears and planetary gears are directly exposed to the outside environment, causing these stones to fly and become stuck between them as the multiple friction discs rotate, thus affecting the device's usability and the grinding of the ground. Therefore, a high-precision floor polishing machine is proposed to solve these problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, such as the presence of numerous gravel particles on the ground after construction, and the exposed gears and planetary gears of the device, which can cause gravel particles to splash and become stuck between the gears and planetary gears due to the rotation of multiple friction discs, this invention provides a high-precision floor polishing machine.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0007] This utility model discloses a high-precision floor polishing machine, comprising a fixed frame, a rotating shaft rotatably connected inside the fixed frame, a bevel gear fixedly connected to the surface of the rotating shaft, a fixed shell fixedly connected inside the fixed frame, the interior of the fixed shell rotatably connected to the surface of the rotating shaft, a drive rod rotatably connected inside the fixed shell, a bevel gear also fixedly connected to one end of the drive rod inside the fixed shell, the surfaces of the two bevel gears meshing with each other, and a friction disc fixedly connected to one end of the drive rod outside the fixed shell, with a polishing pad provided on the side of the friction disc closest to the ground.
[0008] As a preferred embodiment of this utility model, a motor is fixedly connected to the surface of the fixed frame, the output end of the motor is rotatably connected to the interior of the fixed frame, and the output end of the motor is fixedly connected to the rotating shaft.
[0009] As a preferred embodiment of this utility model, a rotating rod is rotatably connected inside the fixed frame, and a brush is provided on the surface of the rotating rod.
[0010] As a preferred embodiment of this utility model, pulleys are fixedly connected to the surfaces of both the rotating rod and the rotating shaft, and belts are drivingly connected to the surfaces of the two pulleys.
[0011] As a preferred embodiment of this utility model, a protective shell is fixedly connected to the surface of the fixed frame, the motor is located inside the protective shell, and the pulley and belt are also located inside the protective shell.
[0012] As a preferred embodiment of this utility model, the fixed frame has a sliding groove inside, a sliding rod is slidably connected to the inner wall of the sliding groove, a roller is provided at the end of the sliding rod away from the fixed frame, and a counterweight is fixedly connected to the surface of the fixed frame.
[0013] As a preferred embodiment of this utility model, the groove is hexagonal and the sliding rod is also hexagonal.
[0014] As a preferred embodiment of this utility model, a return spring is fixedly connected inside the fixed frame, and the end of the return spring away from the fixed frame is fixedly connected to the sliding rod.
[0015] The beneficial effects of this utility model are: This high-precision floor polishing machine, by starting the motor, causes the drive rod to drive the friction disc to rotate and complete the grinding of the ground. The conical gear and other components are set inside the fixed shell, which prevents them from contacting the outside world. This avoids the damage to the equipment caused by flying stones as in the comparative case and protects the equipment. Attached Figure Description

[0022] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0023] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model discloses a high-precision floor polishing machine, including a fixed frame 1. A rotating shaft 9 is rotatably connected inside the fixed frame 1, and a bevel gear 12 is fixedly connected to the surface of the rotating shaft 9. A fixed shell 3 is fixedly connected inside the fixed frame 1, and the interior of the fixed shell 3 is rotatably connected to the surface of the rotating shaft 9. A drive rod 10 is rotatably connected inside the fixed shell 3, and a bevel gear 12 is also fixedly connected to one end of the drive rod 10 inside the fixed shell 3. The surfaces of the two bevel gears 12 mesh with each other. By setting the fixed shell 3, the bevel gears 12 on the surfaces of the drive rod 10 and the rotating shaft 9 are covered, preventing the bevel gears 12 from contacting the outside. A friction disc 11 is fixedly connected to one end of the drive rod 10 outside the fixed shell 3, and a grinding disc is set on the side of the friction disc 11 closest to the ground.
[0024] A motor 15 is fixedly connected to the surface of the fixed frame 1. The output end of the motor 15 is rotatably connected to the inside of the fixed frame 1, and the output end of the motor 15 is fixedly connected to the rotating shaft 9.
[0025] The fixed frame 1 is rotatably connected to a rotating rod 7. The surface of the rotating rod 7 is provided with a brush 8. The rotating rod 7 drives the brush 8 to rotate, sweeping the ground and cleaning the area in front of the friction disc 11.
[0026] Both the rotating rod 7 and the rotating shaft 9 are fixedly connected to pulleys 14. The surfaces of the two pulleys 14 are connected to a belt 13. Thus, when the rotating shaft 9 rotates, the rotating shaft 9 drives the pulleys 14 on its surface to rotate, thereby driving the belt 13. In turn, the belt 13 drives the rotating rod 7 and the pulleys 14 on its surface to rotate, causing the rotating rod 7 and the rotating shaft 9 to rotate.
[0027] A protective shell 4 is fixedly connected to the surface of the fixed frame 1. The motor 15 is located inside the protective shell 4, and the pulley 14 and belt 13 are also located inside the protective shell 4. The protective shell 4 covers the motor 15, pulley 14 and belt 13 to prevent dust generated during floor grinding from covering them and to protect the motor 15, pulley 14 and belt 13.
[0028] The fixed frame 1 has a sliding groove 16 inside, which is a regular hexagon. A sliding rod 5, also a regular hexagon, is slidably connected to the inner wall of the sliding groove 16. A roller 6 is provided at the end of the sliding rod 5 away from the fixed frame 1. The sliding groove 16 and the regular hexagon of the sliding rod 5 limit the sliding rod 5, thereby preventing it from rotating. A return spring 17 is fixedly connected inside the fixed frame 1. The end of the return spring 17 away from the fixed frame 1 is fixedly connected to the sliding rod 5. A counterweight 2 is fixedly connected to the surface of the fixed frame 1. By setting the counterweight 2, the operator can add counterweight to the device, thereby causing the sliding rod 5 to move inward into the fixed frame 1, and the fixed frame 1 to move downward. This ensures that the friction disc 11 can always be in contact with the ground, performing fine grinding on the ground and improving the grinding effect.
[0029] When the floor needs to be polished during operation, the operator starts the motor 15, which drives the rotating shaft 9 to rotate. This causes the rotating shaft 9 to rotate the bevel gear 12 on its surface, which in turn drives the drive rod 10 and the bevel gear 12 on its surface to rotate. The drive rod 10 then drives the friction disc 11 to rotate, which in turn drives the friction pads to rotate and polish the floor.
[0030] When the rotating shaft 9 rotates, it drives the rotating rod 7 in cooperation with the pulley 14 and the belt 13. The rotating rod 7 drives the brush 8 to rotate, which sweeps the ground and removes the stones on the grinding road, thus preventing the stones from contacting the friction disc 11 and causing damage.
[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
